AI tools are increasingly used in imaging, diagnostics, and clinical decision support. Here’s how the FDA regulates artificial intelligence as medical devices, what Software as a Medical Device (SaMD) means, and what patients should know about safety, updates, and limits in 2026.
Artificial intelligence is increasingly used in imaging, heart monitoring, and disease screening. Here’s how the U.S. Food and Drug Administration regulates AI-enabled medical devices — and what that oversight means for patient safety, transparency, and trust.
The FDA continues to monitor rare cancers linked to breast implants, including BIA-ALCL and emerging reports of BIA-SCC. Here’s what patients need to know about symptoms, risk levels, informed consent, and insurance coverage.
OTC hearing aids are now widely available for adults with mild to moderate hearing loss. Here’s what the FDA requires, how they differ from prescription devices, what traditional Medicare does and does not cover, and when a medical exam is still essential.
AI tools are increasingly used in U.S. hospitals and clinics, but not all of them are regulated the same way. Here’s how the FDA oversees AI-enabled medical devices, what clearance really means, and what patients should ask when AI is involved in their care.
